Reproducible: Always

Steps to Reproduce:
1. Start bootstrapping prefix on Mac OS
2. Wait for gcc to almost finish its emerge

Actual Results:  
Failure with described message

Expected Results:  
Successful bootstrapping

do you have -g in your CFLAGS yourself, or is it part of the defaults somehow?

Comment 3 Alex 2021-08-17 10:41:50 UTC

I haven't modified the installation in any way, so it must be a part of the defaults.

Comment 4 Fabian Groffen gentoo-dev

2021-08-27 15:27:15 UTC

I just tried bootstrapping on a stock x86_64-apple-darwin20, which worked fine, need to check the xcode version there to see if it makes a difference.
